摘要:
The invention relates to a programmable controller, comprising an arithmetic unit, a screen (6), an operator unit (4, 5), signal inputs (2) and signal outputs (3). Said arithmetic unit, screen (6), operator unit (4, 5), signal inputs (2) and signal outputs (3) are accommodated in a common housing (1). Switching functions can be programmed by the user using a menue-assisted user interface on the screen (6) and on the basis of pre-set functions. A button of the operator unit (4, 5) can be switched to an active button by a programmable function. The operation of a switching function then depends on the activation of this button.

The invention relates to a cut-out blade magnetic drive for electric switchgears, e.g. contactors. The aim is to overcome the tolerance problems associated with iron components and pre-assembling the device as a compact unit. To this end, a yoke (28), a magnet core (30), a pole plate (32) and a cut-out blade (68) are secured in a coil body by means of a clamping spring exerting a force so as to be self-adjusting and non-detachable. The coil body (34) has parts (76; 82; 83) exerting a counter-pressure against parts of the housing (12, 14) which correctly position the cut-out blade magnetic drive (16) in relation to its limits of travel (A; B) within the housing (12, 14).
摘要:
Die Erfindung betrifft eine Betätigungsvorrichtung zum Ein- und Ausschalten von Leistungsschaltgeräten, insbesondere für mehrphasige Motorschutzschalter. Das zu lösende Problem besteht darin, die Betätigungsvorrichtung nach Wahl durch einen Drehknebel oder durch Drucktasten zu betätigen. Dazu ist ein Gehäuseoberteil (61; 62) vorgesehen, das mit dem Gehäuseunterteil (4) zu verbinden ist und wenigstens das Schaltschloß (3) abdeckt. Ein vor das Gehäuseoberteil (61) zu setzendes, als Drehknebel ausgebildetes erstes Betätigungsmittel (21) steht in Wirkverbindung mit der Betätigungswelle (31) des Schaltschlosses (3). Ein im Gehäuseoberteil (62) gelagertes, als jeweils eine Drucktaste zur Handeinschaltung bzw. zur Handabschaltung (221 bzw. 222) ausgebildetes zweites Betätigungsmittel (22) steht in Wirkverbindung mit der Schaltkulisse (32) des Schaltschlosses (3), wobei die Drucktasten (221, 222) hinsichtlich der Drehachse (321) der Schaltkulisse (32) entgegengesetzt wirken. Wahlweise ist das erste oder das zweiten Betätigungsmittel (21 bzw. 22) einsetzbar.
摘要:
The invention relates to an electromagnetic switch magnet control system (1) for contactors (2). The contactor (2) has a coil (7) which drives switching contacts (5) via an armature (4) moving between an ON and OFF position. The switch magnet control system (1) also has a sensor (S, 3a) used to determine the position of the armature (4) driven by the coil (7). A mark (4a) joined to the armature (4) can be detected by the sensor (S, 3a). The sensor (S, 3a) is arranged with respect to the mark (4a) in such a manner that when the armature (4) deviates to a small extent from the ON position the sensor (S, 3a) detects the mark (4a) and sends an appropriate signal to the switch magnet control system (1). So, a maximum magnetic field is generated which drives the armature (4) towards the ON position as soon as the sensor (3; S, 3a) detects the mark (4a), the strength of said maximum magnetic field being set or adjusted for a predetermined maximum time (tmax) and cut off at the end of said maximum time (tmax).
摘要:
The invention relates to a low-voltage power switch with a relative auxiliary switch which is actuated as a signalling switch only when the generally multi-pole low-voltage power switch is triggered. The problem to be solved is that of controlling relative auxiliary switches simply and independently of the switch latch. To this end, the switch latch is designed in such a way that the included angle of the movable contacts or the switching spindle (18) is greater in the 'triggered' than in the 'off' state. A radial extension (60) is arranged on the switching spindle (18) in such a way that, in the 'triggered' state, it engages a fixed pivoted lever (68) which itself is effectively connected to the prestressed actuating pushrod (66) of the relative auxiliary switch (56).

The invention relates to a protected switch (1) with a housing (6) and a rotatable control grip (3) securable against switching on by at least one padlock. A cover (2) large enough to cover the control grip (3) and lockable by means of the padlock(s) is foldably fitted to the housing (6). In the cover (2) there is a recess (22) into which the control grip (3) can be received. The recess (22) can be set to its off position in accordance with the position of the control grip (3) with the contacts of the protected switch (1) fully open and the control grip (3) can be received into the recess (22) in the cover (2) only in its off position, and the cover (2) can be moved into the closed position, where it can be locked by means of the padlock(s) only with the control grip in the off position.

The invention concerns a lock for a power switch, the lock having a gate, two elbow levers connected to each other by a spindle, a spiral locking spring and a release arm which controls the tipping point and hence the release of the switch shaft.

The figure shows a length of busbar (1) carrying elongate conductors (2, 3, 4, 5) extending beyond the end of said length and straddled by two side plates (6) and (7) which provide means on which a cover may be mounted. The side plates (6, 7) are fastened to a joint pack (2) with said plates extending into slots (9, 10).
